Zenith jet sizes

Posted by Steve Watrous on May 14, 1998 at 16:43:45

Can anyone tell me how to correlate the numbers on Zenith jets to the diameter of the jet orifice?I understand that the jets were originally metric and that the stamped numbers indicated the diameter in millimeters.I want to try my hand at really rebuilding my carb and would like to be able to accurately size the jets.Thanks.
